Long-Term Liquid Silicone Rubber Supply Partner: Reliable Sourcing for High-Performance Applications

Long-Term Liquid Silicone Rubber Supply Partner: Reliable Sourcing for High-Performance Applications

Dongguan Times Silicon Industry Co., Ltd. is a specialized manufacturer of liquid silicone rubber (LSR) and other silicone materials, founded in 2021 and headquartered in Dongguan, Guangdong. The company supplies certified LSR grades for new energy, medical, electronics, and industrial applications, offering a monthly production capacity of 80 tons that can scale to 110 tons during peak seasons. This page outlines why a long-term supply relationship with Dongguan Times Silicon ensures consistent quality, compliance, and supply security for demanding projects.

The Challenge: Securing a Stable Long-Term LSR Supply

Procurement teams evaluating a long-term Liquid Silicone Rubber supply partner in China face three core risks: batch inconsistency, regulatory non-compliance, and supply interruptions. These risks directly affect product reliability, time-to-market, and total cost of ownership. To mitigate them, a supplier must demonstrate verified capacity, certified compliance, and transparent process control.

Industry Context: Growing Demand for High-Performance LSR

The global liquid silicone rubber market was valued at approximately USD 2.8–3.8 billion in 2024, with projections to reach USD 5.0–7.55 billion by 2030–2035 (Grand View Research, GMI). Medical-grade LSR alone generated roughly USD 458.7 million in 2024 (Grand View Research), while about 63% of EV battery pack sealing systems already rely on silicone elastomers (Precedence Research). These trends increase the importance of selecting a supplier that can deliver both standard and custom formulations under strict deadlines and quality frameworks.

Solution: Dongguan Times Silicon as Your Long-Term LSR Partner

Dongguan Times Silicon Industry Co., Ltd. offers a full spectrum of liquid silicone rubber solutions with verified compliance and flexible production. The company operates a 15,000 m² factory, employs 10 R&D engineers, and holds ISO 9001 certification. All products are tested against RoHS, REACH, FDA, LFGB, and halogen-free standards. Through its wholly-owned subsidiary, Guangdong Times Energy Storage New Material Technology Co., Ltd. (founded 2023), the group focuses on high-end new energy silicone materials such as foamed LSR, ceramicized LSR, and thermally conductive LSR.

Production Capacity and Lead Times

Monthly production capacity is 80 tons, scalable to 110 tons for peak seasons. Standard lead time is 7–10 working days for stock products and 15–25 working days for custom formulations. Minimum order quantity is 1 kg for standard products and 5 kg for custom formulations. This low MOQ enables clients to validate formulations before scaling, reducing new product introduction risk.

Quality and Consistency Management

The company follows ISO 9001 SOPs for raw material inspection, in-line viscosity/hardness monitoring, and full finished‑product testing. For critical applications, each batch is tested for curing behavior, odor, yellowing, and biocompatibility. Batch retention is maintained for three years, ensuring traceability. The risk‑control system (see risk unit) covers insulation failure risks, compliance risks, and aging stability—supported by third‑party test reports.

Performance Advantages Over Conventional Silicones

For demanding applications, Dongguan Times Silicon’s LSR grades outperform typical industrial or recycled silicones. For example, its adult‑product LSR (TS6825A/B series) achieves tear strength ≥35 kN/m, no detectable odor, and no yellowing after 1,000 hours of accelerated aging—compared to ≤20 kN/m and severe yellowing after 200 hours for low‑quality alternatives. The platinum catalyst used allows addition rates of only 5–10 ppm (versus 50–100 ppm fororganotin catalysts), reducing overall formulation cost by 10–15% while eliminating residual odor.

Step-by-Step: How to Engage as a Long-Term Partner

1. Submit inquiry through website or email with target application, required properties (hardness, tear strength, elongation), and volume forecast.
2. Formula review – R&D team (10 engineers) suggests existing grade or custom formulation. Free sample (1 kg) provided for testing.
3. Sample validation – Customer performs in‑house or third‑party testing. Lead time for samples: 7–10 days.
4. Pilot production – First batch (5–50 kg) produced under controlled parameters. Hardness, curing speed, and batch consistency verified.
5. Scale to volume – After pilot approval, production ramps to full scale with dedicated line if volume exceeds 5 tons/month. Ongoing monthly quality reports shared.
